To all whom itinay concern:

Be it known that I, James W. GUILLOIT, a citizen of the United States,residing at Chicage, county of Cook, State of Illinois, have 5 inventeda certain new and useful 1m rovement in Gaskets; and I declare the foowing to be a full, clear, and exact descri JlilOIl of the invention,such as will enable 0!; ers skilled in the art to which it pertains tomake and to the aceompanying drawings, which form a part of thisspecification.

My invention relates in general to gaskets, to metallic gaskets, orforming joints betweensections of conduits for carrying fluids at highpressure. The rapid deterioration of rubber and fabrics when exposed tosteam, ammonia-and s prevents the use of rubber or fabric gaskets in thejoints of conduits adapted to carry such fluids. It has therefore beenproposed heretofore to employ metallic gaskets either in the form ofwashers or corrugated annular disks. The use of solid metallic askets isnot only d unsatisfactory, as the resulting joint is so ri id that theexpansion of the sections when eated at, the oint o breaks the boltsuniting the flanges around the adjacent ends of united sections or elsecracks the flanges themselves. Corrugated metallic gaskets as heretoforeconstructed are objectionable, for the reason that the corfiattened byetween which thereby permiteakage when the flanges contract; The primaryobject of m invention is to ie gasket which will not be permanentlyflattened when compressed between the ends of the united sections of aconduit, but which will be sufficiently resilient to maintain a closecontact the compression of the flan cs 5 between the ends of the unitedsections when they separate by contraction, thereby forming apermanently tight joint.

A further object of my invention is to provide a gasket which will besimple in con- 50 struction, inexpensive in manufacture, and

efficient and durable in use.

The herein-disclosed emhodiment 'f my invention, generally described,consists a metallic annular disk having concentric cor- 5 5 rugationsand metallic" rings united to the inner and outer edges of the disk,thereby in- Speciflcation of Letters Patent.

Similar reference characters are t designate similar parts in theseveral figmes of the drawings.

A designates a metallic asket consisting in an annular disk providedwith concentric corrugations. The openin 5 through. the gasket may be ofany desire diame to cor respond with the diameter of the conduit betweensections of which the gasket is to he in serted to form a joint. Theexterior die-me ter of the-gasket may be varied to conform to thediameter of the-usual circular flanges which surround the ends of theconduit-sec tions and through which securin -bol s passed.

By reference to Fig. 2 it will be seen that a ring of metal, is locatedconcentrically around the gasket and is located within a fold 1,preferably formed integrally with the metal 0? the gas ct. An inner ringB is lo cated within a fold 6 around the inner edge of the asket. Thecorrugations formed in the gas et between and concentric with the innerand outer rings rnav be of any desired number and depth;l)ut l havefound in prac ties that it is preferable to have some of thecorrugations-as, iorinstance, A. and at? pro'ect beyond the plane of thelil'lgS B and 13, while other of the corrugations, such as A and A,project in an 0 aposite direction, but to a less extent than t "e planeof the-opposite sides of the rings B and B One or more of thecorrugations-as, for in stance, il -preferably projects in the samedirection as the corrugations A and A, but to an extent beyond the planeof the B and B I The gasket constructed substantially as 7 i, so that,when the saryw 6 0 1 nyccmpmssed, PERU-$511821 as 1;, 5' A if, weggmduced by the dispiaaced e g file others pro- 20 139.9 of such "a inbenching no a of the 's iLUL Lu in 2?, in 1 SHOW mmoved 55mm 0"L.uii,ssc'ti0ns bet-ween the mm. working nutba w: men the flanges ingprefezn'gbiy 11 me outer rang,
